BEVERAGE -CARBONIZER.

SPECIFICATION forming part of Letters Patent No. 422,203, dated February25, 1890.

Application filed August 16, 1889 Serial No. 320,976. (No model.)

T0 at whom it may concern.-

Be it known that I, OHAUNGEY W.. GIBsoN, a citizen of the United States,residing in the city and county of San Francisco, and State ofCalifornia, have invented a new and useful Improvement inBeverage-Oarbonizers, of which the following is a specification,referings and the letters referring thereto.

Figure 1 is a perspective view showing one center; Fig. 2, a sectionalview of the automatic pressure-regulator5 Fig. 3, a perspective view ofthe automatic pressure-regulator.

A represents the pressure-chamber which supplies the gas to thefountain; B, the pipe which connects the pressure-chamber andpressure-regulator; O and D, the two parts forming the case of thepressure-regulator; E, the pipe which connects the pressure-regulatorand fountain; F, the valve which is opened and closed by the pressure ofthe gas in the fountain to regulate the supply of the same; G, thediaphragm which operates the valve F to open and close the same, aswillbe shown; H, the fountain; I and J, the pipes connecting the fountainwith any suitable dispenser; K, the agitator for thoroughly mixing thegas with the liquid, as will be shown; L, the point of the spindle,which serves as the journal for the agitator; M, the step in which thepoint or journal of the agitator revolves; N, the collar in which the upper journal of the agitator revolves; O, the guide-supporting rim; 1?,the centering-guide to direct the service-pipe I centrally when beingplaced down into the fountain; Q, the pipe for filling the fountain; R,the cap for the pipe Q; S, the vent and overflow-valve; T, the plug forclosing the opening through which the valve F is placed, and by'means ofwhich it is readily reached for the purpose of regulating the requiredpressure in the fountain; U, the connecting-block for the valve stem toconnect the same with the diaphragm; V, the nozzle through which the gasis discharged against the wings of the agitator; W, the arms whichconnect the stirrer or agitator with its point-journal.

The following is the construction of" my improved beverage-carbonizer: Iemploy a p ressure-chamber A, of steel or other strong metal, to safelycontain a pressure exceeding six hundred pounds to the inch. I producethis chamber A in a cylindrical form, as shown, and about the height ofthe fountain which it supplies, for convenience of construction andoperation of the system. The reservoir A is generally charged with gasat a pressure exceeding six hundred pounds to the inch.

I construct the fountain of such metal as is generally employed in thatclass of manufacture.

I connect the automatic pressure-regulator O, D, F, G, and U with thepressure-reservoir A by any suitable pipe B. I form thepressure-regulator of metal and screw the parts 0 D (which form thecase) together with the diaphragm clasped and made perfectly tight withan ordinary lead-joint.

The following is the operation of my improved beverage-carbonizer forthe purpose of thoroughly mixing the gas with the liquid and maintainingany required pressure equal in degree from the first until the fountainis empty of liquid: To illustrate more clearly how this is effected, Iwill here particularly describe the construction and operation of thediaphragm and valve. I form the diaphragm of good springy sheet metal,which will allow a movement or vibration sufficient to close the valve Fwhen the pressure is applied to the same. When there is no pressureagainst the diaphragm, the valve F stands open, as shown in Fig.2, andas the pressure is appled it is gradually drawn down to its seat. 7 henit is required to'increase or diminish the pressure in the fountain, theplug T is taken out and the valve F is either screwed in or out, asrequired, thus requiring greater or less motion of the diaphragm and acorresponding variation in the pressure brought against the diaphragm.It must be understood that the pressure in the reservoir Ais sufficientto insure a surplus after the fountain has fully discharged its liquidcontents. lVhen the fountain is filled with the liquid, the vent oroverflow-valve is open. The liquid is poured in throughthe pipe Q untilit overflows at the Vent -S, the pipe Q extending below the vent oroverflow-valve S. The part of the fountain above acts as an air-chamberand prevents the liquid from going in above that point. cures adetection of any leak when the cap R is placed upon the pipe Q, as thegas cannot escape without forcing out the liquid, as will be readilyseen from the position of the lower end of the pipe Q, as shown. Thusprepared, the fountain is closed up tightly and opened through thenozzleW to receive its charge of carbonic-acid gas, which being drivenwith great force against the wings of the agitator K, it is revolved andthoroughly agitates and mixes the gas with the liquid in the fountain.

When it is required to open the fountain and get at the interiorconstruction of the same, it is separated at the flanges in'the centerand the pipes I and Q withdrawn with the upper portion of the fountain.The guide P secures the centering of the pipe I and guides it downthrough the cent-er of the agitator K. It is bolted together in theusual manner for connecting articles of that class of manufacture.

Having thus described myinvention in bev- It also se--erage-carbonizers, what I claim, and desire to secure by Letters Patent,is

1. The combination of a fountain, a rotary agitator journaled therein,provided with a hollow spindle having a pivotal point in axial linetherewith, an opening between said spindle and point, and a dependingtube passing through the hollow spindle and having connections with saidopening and the fountain discharge-pipe;

2. The combination of a fountain having a discharge-pipe, a rotaryagitator journaled therein, and guides, as O and P, for centering thedischarge-pipe and agitator.

3. The combination of a fountain, an agitator having a hollowjournal-bearing and pivoted at one end in said fountain, and aremovablepipe-connection extending into the fountain and agitator andconstituting another bearing for the agitator.
